Amazilia yucatanensis, Elliot, Syn. Troch. p. 219 (partim) ”

viridi lavatis, margine pectoris postico viridi male definito. 
Q mari similis. (Descr. maris et femine exempl. typ. ex Cordova, Mexico. Mus. Brit.) 
Hab. Texas °7,—Mexico, Presas de Aldama, Altamira, Tampico, Tantina in Tamau- 
lipas (W. B. Richardson ®), Valles in San Luis Potosi (W. B. &.°), Misantla, 
Colipa (F. D. G.%), Vega del Casadero, Tomatla (IM. Trujillo °), Jalapa

Vera Cruz and Laguna near Vera Cruz (W. B. Richardson®), Sochiapa 
(M. Trujiilo °). 
Gould described this species from some of M. Sallé’s specimens obtained near 
Cordova, where the bird is now known to be common, and it has been traced south- 
wards to Sochiapa near Playa Vicente and northwards throughout the States of Vera 
Cruz and Tamaulipas across the Rio Grande into Texas. It does not appear to be 
found inland much beyond the eastern slope of the mountains of these States, Valles 
in the State of San Luis Pctosi being the furthest point from the coast. Its presence 
on the northern side of the Rio Grande was first announced by Dr. Merrili in 1877 °, 
and it is now known to be a common bird near Brownsville, whence Mr. Armstrong 
has sent us many specimens. 
The distinctness of A. cerviniventris from <A. yucatanensis was questioned by 
Mr. Elliot 1°, but its status was re-established by Mr. Ridgway ®, and there can be no 
doubt, we think, that the two birds are quite distinct.
